NAME
Regexp::Grammars::Common::String - Some basic String parsing Rules for
Regexp::Grammars
VERSION
version 0.01000002
SYNOPSIS
use Regex::Grammars;
use Regexp::Grammars::Common::String;
my $re = qr{
(.*)+
}x; # don't forget the x!
...
if( $content =~ $re ){
print Dumper( \%/ ); # Praying Mantis operator!?
}
DESCRIPTION
Regexp::Grammars is just too useful to not use, but too pesky and
confusing for new people.
Some of the more complex things involve string extraction and
escape-handling, and I seriously spent the better part 2 hours learning
how to make this work. So, even if this module is not immediately
useful, it may serve as an educational tool for others.
I probably should have delved deeper into the Regexp::Common Family, but
I couldn't find one in there that did exactly what I wanted.
At present, this module only provides one rule, "String", but I will
probably add a few more later.
GRAMMARS
Regexp::Grammars::Common::String
RULES
String
For parsing strings like so:
"Hello" => 'Hello'
"Hel\lo" => 'Hello'
"Hel\\lo" => 'Hel\lo'
"Hel\"lo" => 'Hel"lo'
It should do a reasonable job of picking up strings from files and
properly returning their parsed contents.
It made sense to me to drop the excess "\"'s that are used for escaping,
in order to get a copy of the string as it would be seen to anything
else that parsed it properly and evaluated the escapes into characters.
